Il territorio è sotto pressione e il suo sfruttamento non è più sostenibile, come risulta dal primo rapporto sullo stato del suolo svizzero, pubblicato dall'Ufficio federale dell'ambiente.
Terreni sani sono una condizione fondamentale per la sicurezza alimentare e rappresentano una base vitale. Malgrado ciò, sono la risorsa più sottovalutata e meno considerata, si legge nel relativo comunicato.
Le sollecitazioni a cui sono sottoposti sono note (impermeabilizzazione, erosione, compattamento), ma finora erano disponibili solo informazioni frammentarie, raccolte grazie a singoli progetti di ricerca. Ora tutti i dati e le conoscenze sul tema sono riuniti.
